Crossing the threshold: New Systems Instruments’ “discrete map”

video upload by Electrum Modular

"New Systems Instruments sent me their new module, Discrete Map. It’s a deep module, with lots of potential uses, so I’ll be dedicating the next few videos to it. This first, introductory video uses it as a generative sequencer, extracting an evolving melody from a Lorenz chaos trajectory."

"Novum! New Systems Instruments has created a unique and innovative approach to generating sequences with Discrete Map.

New Systems Instruments consistently surprises with innovative designs! Discrete Map fits right in, taking a simple concept and turning it on its head. At its core, it’s an 8-step sequencer that can output a traditional step-by-step sequence. The pitch values are set using the eight upper faders, but what makes it truly special are the eight lower faders, which determine which step is played at any given moment.

The sequencer’s X input accepts any signal, a clock, an LFO, or even another sequence. The lower faders set threshold values, and the switches below them define whether they react to a rising or falling edge. This means the sequence jumps to different steps based on the incoming signal, creating a highly controllable form of randomness! The results are striking! Complex rhythms and surprising melodies that become even more dynamic when paired with the expander for voltage-controlled step selection.

Discrete Map also includes an onboard oscillator. A switch toggles between a slow and fast frequency range. When slow, it functions as a standard step sequencer. Another switch changes from Position mode (explained above) to Length mode, where the lower faders control step duration. When switched to the fast mode tho, it becomes a graphic oscillator that tracks V/Oct.

To round out the package, Discrete Map includes additional utilities for better integration with other modules. The precision adder for example allows an external voltage to transpose the entire sequence.

The A/B/C Expander further enhances functionality, adding three assignable groups for the steps. Each group gains CV-controllable threshold values and dedicated gate outputs for active steps. And because that´s not enough there's also a sequential switch. Several discrete maps and A/B/C expanders can be linked together!

Overall, an incredibly well-thought-out and entirely fresh approach to sequence generation!

Bend & Twist Time with Voltage Addressed Sequencing // Discrete Map from New Systems Instruments

"Here’s the new Discrete Map and expander from New Systems Instruments. Deeply routed in influence from the Buchla MARF & a Serge Modular style approach to sequencing, coupled with a heady mix of physics and electronics (as New Systems Instruments do so well) the Discrete Map allows you to use voltages to bend and manipulate a time map across 8 stages of voltages. From basic to more advanced sequencing, unique time and rhythm creation to some bonkers graphic VCO applications there’s a lot we get into in the video."
